"Anyone who agrees to be interviewed must decide where to draw the line between what is public and what is private," Gross says. "But the line can shift, depending on who is asking the questions. What puts someone on guard isn't necessarily the fear of being 'found out.' It sometimes is just the fear of being misunderstood."

... to me these are really, really, really important issues.

... the claim that everybody sees the world differently, is not a claim that there's no reality. It's a different kind of claim. What really surprised me on re-watching Rashomon is that you know what really happened at the end. It's pretty damn clear. Kurosawa gives you the pieces of evidence that allow you to figure out what really happened. So, it's not what many people imagine it to be, but it is a very powerful story about self-interest, about wishful thinking, about self-deception, about people imagining scenarios at variance with the truth. And so I found Rashomon to be far more interesting than I had remembered it. With an underlying theme very much like The Thin Blue Line. Truth exists, but people have a vested interest in not knowing it.

I was surprised at the time that The Thin Blue Line came out that people reacted to the reenactments as blurring the distinction between fact and fiction. Between documentary and drama. My feeling was the exact opposite. It was telling us how images can confuse us. Images are not reality, nor do I claim that they are. In fact, they usually bear a very complicated relationship to reality. And when people talk about reenactments, I like to point out that consciousness, itself, is a reenactment. Everything is a reenactment. We are reenacting the world in the mind. The world is not inside there. It does not reside in the gray-matter of the brain. Think of my movies as heightening our awareness, not confusing the difference between truth and fiction, but heightening our awareness of how confused we can become about what is real. Take the first line in Vernon, Florida: "Reality. You mean, this is the real world. I never thought of that."

It's often been said that WW1 created who we are today: geopolitically and culturally. Robert Harris explains how music -- classical and popular -- both prefigured and reflected the war in the years leading up to the unprecedented destruction and after.
